If your dog weighs between 1kg and 10kg, they will fall into this category and require a food specially formulated for small, toy and miniature breeds to satisfy their high energy levels, dental needs and skin and coat health. Because they mostly live indoors, smaller breeds can be prone to skin irritation and weight gain. Popular smaller breeds include Chihuahuas, Toy Poodles, Cavalier King Charles Spaniels, Dachshunds and Miniature Schnauzers.
